Pneumatic Nail Guns
• Pneumatic nailers use compressed air power to set many nails very quickly.
• Their design eliminates the need to grab and hold the nail.
• When operating a pneumatic nail gun, the nose of the nailer must be depressed against a firm surface before it will fire.
Pneumatic Nail Guns - Safety• Proper PPE is required
• Ear protection, safety goggles, hard hat
• Never point the nail gun at your own body or towards anyone else
• Before using a pneumatically powered nailer for the first time, it is important to read the manufacturer’s instructions.
• Before attempting repairs be sure to disconnect the tool from the air hose.
Powder-Actuated Nail Guns
• Powder-actuated tools are excellent when there is no air or electric power.
• They can fire fasteners directly into concrete, which is their primary use.
• Alternative methods (drilling and anchors) are much more labor-intensive.
Powder-actuated nailers act as a low-velocity fastening system that is used to drive steel pins
or threaded studs into masonry and steel.
Powder-Actuated Nail Guns -Safety
• Proper PPE is required• Ear protection, safety goggles, hard hat
• Never point the nail gun at your own body or towards anyone else
• Always make sure to select the proper size pin for the job and never load the tool until it is time to fire
• Special training and certification is required before using any kind of powder-actuated fastening tool
Pavement Breakers• Pavement Breakers are well
suited for breaking up concrete during demolition work.
• A typical pneumatic model weighs between 50 and 90 pounds (20 to 40 kg).
• Consider what is under the area being broken up, such as wiring or piping.
Pavement Breakers - Attachments•A variety of attachments
are available for pavement breakers, depending upon the task.
Pavement Breakers - Safety
•Wear the appropriate PPE• Gloves, hard hat, ear protection
eye protection, boots
• Follow the tool manufacturer’s guidelines
•Know what is underneath what your breaking up (power lines, gas lines, water, sewer)
Jacks
• Jacks can be used for various tasks, such as raising equipment for the installation of permanent footings and vibration isolators.
• A jack should never be depended upon to hold a load
• Lift, position supporting materials, and then remove the load from the jack.
Hydraulic Jacks
• Hydraulic jacks use the transfer of liquids to lift heavy material
• A Porta-Power is an example of a hydraulic jack
